It is not in the program but in the food you eat. To increase strength you mainly have to focus on low reps. Pick one main exercise for each musclegroup and do 5-6 sets of 3-6 reps. Then you pick 2-3 extra exercises for each musclegroup and do 2-3 sets of 8-12 reps. That should do it.

By the way, are you looking for a 2-split or a full body workout?
